How Long Does Herpes Stay Dormant Before First Outbreak?

Herpes can remain dormant for 2-20 days before the first outbreak occurs after initial infection. The incubation period varies significantly between individuals, with most people experiencing their first symptoms within 2-12 days of exposure. However, some people may not develop symptoms for weeks, months, or even years after infection. Studies show that approximately 87% of people with HSV-2 are unaware they have the virus because their symptoms are so mild or nonexistent. During the dormant period, the virus travels along nerve pathways to establish latency in nerve clusters. Even without symptoms, the virus can still be transmitted to partners through viral shedding.
